1. Confidence Intervals = Z intervals on your Calculator
We also have a Z-score
It tells you the probability of that score occurring from 0 to 1
How do you Calculate it:
(X – (mean)) / standard deviation
If it is Positive it is greater than 50%
If it is negative it is less than 50%
You can find a Z-score table anywhere on the internet if googled
I will give you 5 points extra credit if you add it as a separate slide with the correct Z-scores for Question #1’s variables (max & min for both L1 and L2)
Include a summary of what the z score means
